Amir Khan has said he will announce his new trainer on Saturday after confirming his split from Freddie Roach in the early hours of the morning. There had been speculation the pair would go their separate ways after Khan suffered a fourth-round stoppage loss to Danny Garcia for the WBC and WBA light-welterweight titles in July.

Khan wrote on his Twitter account on Saturday: "Officially I've left Freddie Roach. Just spoke to him and had a good professional chat and maybe in the future we work together. Freddie understood why I'm looking at other trainers and wished me all the best for the future."

Roach told ESPN.com: "He said: 'I know you're busy with your other fighters and I'm going to go in a different direction'. He said: 'No hard feelings, maybe we'll get back together someday'. He was being nice. I wished him luck. I've been fired before."

The defeat against Garcia was Khan's second consecutive loss. The Bolton fighter was beaten via a split decision in December last year against Lamont Peterson, who later failed a drugs test which forced the postponement of a scheduled rematch.

Khan said in the aftermath of his defeat to Garcia that he was keen on remaining loyal to Roach, who took charge of the 25-year-old after his knockout loss to Breidis Prescott in September 2008 and led him to two world titles in the 140lb division.

However, Khan wanted guarantees that Roach, who also looks after Manny Pacquiao, would be fully focused on the Briton for the duration of pre-fight camps.

While the two seem to have been unable to come to a resolution, Khan's statement suggests his split from the owner of the famous Wild Card boxing gym has been an amicable one.

Roach is in Las Vegas with another one of his charges – Julio César Chávez Jr, who defends his WBC middleweight title against Sergio Martinez of Argentina on Saturday night.
